I think this would hold up better if refusing to give consent didn't end with you being fired on the spot. All of a sudden with no warning you're now not getting your next paycheck. That sounds like duress to me. I would be much more likely to agree with you if the employer came out and said "here's the new policy, it's being implemented in 6 months. On this date 6 months in the future, you need to sign this form or you're out." That gives you time to make other arrangements, get independent review of the policy, whatever you want.
